Study or Job ?
There are two options you prefer after you complete your B.Tech degree. If you are economically efficient and don’t need a job, it is better you go for your further studies. A specialization will always earn you more salary as well as priority during interviews and of course sound grip over subject. Otherwise you can find some job.
Further Studies:
If you prefer to continue to studies, you can do Post graduate courses and then obtain a Ph.D. You have lots of options during this P.G course like M.S/ M.Tech, IAS/IPS, Navy/NDA and Finance related courses like MBA.
M.S/M.Tech:
Entrance exams for Post Graduation in Engineering Courses.
If you prefer doing P.G in your field of study, you can go for M.S/M.Tech. If you are ready to go outside India and financially sound you can prefer M.S. You need to appear for GRE/TOEFL for doing M.S in Foreign countries.
GRE: The Graduate Record Examination or GRE is a standardized test that is an admissions requirement for many graduate schools in English speaking countries. It is created and administered by the Educational Testing Service and is similar in format and content to the SAT. It is a computer based Online Test. The percentile scored in this exam will decide your future in doing M.S in foreign nations
TOEFL: The Test of English as a Foreign Language (or TOEFL®, pronounced "toe-full" or sometimes "toffle") evaluates the potential success of an individual to use and understand Standard American English at a college level. It is required for non-native applicants at many English-speaking colleges and universities. A TOEFL score is valid for two years and then is deleted from the official database.
The TOEFL® test is a registered trademark of Educational Testing Service (ETS®) and is administered worldwide. The test was first administered 1964 and has since been taken by nearly 20 million students.
Since its introduction in late 2005, the Internet-based test (iBT) has progressively replaced both the computer-based (CBT) and paper-based (PBT) tests. The iBT has been introduced in phases, with the United States, Canada, France, Germany, and Italy in 2005 and the rest of the world in 2006, with test centers added regularly.
The demand for test seats remains very high even after almost a year after the introduction of the test: Candidates have to wait for months since short-term test dates are fully booked. The four-hour test consists of four sections, each measuring mainly one of the basic language skills (although some tasks may require multiple skills) and focusing on language used in an academic, higher-education environment. Note-taking is allowed in the iBT.
GATE: Conducted by one of seven Indian Institutes of Technology in rotation, Graduate Aptitude Test in Engineering (GATE) is an annual exam for admission to M.Tech and M.S. programmes in most engineering institutes in India[citation needed]. It is regarded as a benchmark test for engineering graduates in India [citation needed]. This examination is coordinated by a committee, comprising of Indian Institute of Science, Bangalore and seven Indian Institutes of Technology on behalf of the National Coordinating Board - GATE, Department of Education, and Government of India. The pattern and syllabus are usually based on a candidate's B.Tech. Or BE syllabus. Minimum eligibility for appearing in this exam is usually a B.Tech, BE, B. Arch. or Masc. The exam is usually conducted on second Sunday of February.
PSU's like BARC, NPCIL, HAL etc. give importance to GATE scores for various job positions in their organizations.
It is not worthy for anyone doing P.G in some college other than Foreign/Indian University Colleges, and Premiere Private Engineering Colleges
MBA:
Entrance exams for Post Graduation in Management Courses.
If you prefer doing P.G in some finance related courses you can definitely go for MBA.
GMAT: The Graduate Management Admissions Test, better known by the acronym GMAT (pronounced G-mat), is a standardized test for determining aptitude to succeed academically in graduate business studies. The GMAT is used as one of the selection criteria by most respected business schools globally, most commonly for admission into an MBA program.
The GMAT is one of many factors schools use when reviewing applications for admission; it is typically balanced with work experience, grades in previous schools, recommendation letters and other admissions criteria.
The fee to take the GMAT is currently US$250, worldwide.
Global institutes like ISB require the entries to write GMAT.
CAT: Common Admission Test is conducted by IIMs in India for entry to various IIMs present in India. Admissions are based on the scores in CAT exam.
Indian Civil Service:
write UPSC Exams
The Indian Civil Service serves as the backbone of India and carries great respect and responsibilities. India's best brains vie for entry into the Indian Civil Services as officers. Even though corporate jobs may offer the best of salaries and perks, a majority of youngsters and their parents still crave entry to the prestigious Indian Civil Services held by the UPSC. The very fact that a big share of every year's top posts in the civil services exams are bagged by professionals from various streams, shows that the IAS is still the dream job for many
These are most preferred routes by engineering students in education after B.Tech
Job/ work:
Software industry:
What ever the branch you are in during your engineering you can get into a software industry with simply communication skills. It is good if you get a job during the campus placements itself because it is really difficult to find a job after you come out of the college. However there are various kinds of jobs in Software industry which you get accordingly as your course of study or your specialization. It is ok if you do job for sometime and start studying again for your P.G courses.
Own Company:
If you are financially sound, you can start your own company with a little experience in some other company.
Still there are various choices in jobs like lecturer in some famous engineering college, call center jobs, etc.
Conclusion:
So decide your career now it self and prepare accordingly to reach your goal
